Intel don't have vpintersect. Its micro-coded dog slow but its such an obscure operation and of little use if any. I'd rather AMD re-invest the hardware into speeding up useful operations, shave 1 cycle off divide or square root o

Get-ItemProperty : Cannot find path 'HKCU:\SOFTWAREMicrosoftIdentityCRLExtendedProperties' because it does not exist. At line:1 char:7 I guess I'm good then.

It went from ~30ns to 2K ns but mostly timed out when I changed the alignment to +7.5 QWORDs on Golden Cove.

Small indian. Starting at zero and extending is logical. Big indian is dumb and confusing.

I found a jpeg2000 reference PDF somewhere. It may as well have been written in Mandarin. I got as far as extracting the width and height. Its much more advanced than jpeg. Forget about writing a decoder.

Heh. 1.Create fast modulus quad M for dword D for the first 2000? 200000? (x M) D 2.Eliminate 0b,101b 3.Divide using vrcp14ss/vdivss with correction. Use fast square root too using rsqrt14.

Human hearing is excellent. Good directional perception and sensitivity. Eyesight is the weakest sense. Poor color sensitivity, low light sensitivity, blindspot. The terrible natural design flaws are compensated by natural nystagmas and the

Britain should have stayed neutral like Sweden and Switzerland instead of getting economically devastated.

x87 should have been killed off. It would have forced lazy game developers to use SSE around the 2005 era.

Its not hype. There's no such thing as AI. Matrix multiplication isn't intelligence.

Already done ages ago. Nothing more of interest. The bottleneck are the 3 conditionals: - positive or negative - positive or negative exponent, x > 10.0 - correction for 1.xxxxx * 2^Y => fract(log10 (2^Y)) 1.xxxxxxxx > 10.0

Baldur's Gate linux native build performed poorly on Gamers Nexus tests. Where's a proper comparison between the fastest linux OS "CachyOS" and Windows 11 LTSC with all the crap removed, particularly the biggest offender

Testmem5 is in a league of its own yet its unclear how. Maybe the AWE table is prone to corruption. Theres nothing special about the internal workings. It doesn't use fences or clflushes.

Is there a simple way to get the "Legacy Console" back without having to format and reinstall windows? Installing packages / the windows modules installer is broken.

Xorshift, LCM and hardware rdrand work just fine. PCG and Weyl are overkill.

I see what you're doing. 13 bytes, 3 cycles. Why does newline not work? lzcnt ecx,ecx mov eax, 00100 0011 0010 0000 0001b shl ecx,2 shrx eax,eax,ecx and eax,15

I have low pitch rumbling in my right ear. MRI was useless. Hearing test "perfect". Its hard to sleep without background noise. I think its a damaged blood vessel in my brain or neck: veinous stenosis.

The UK is going downhill. Economically and politically. Use of government thugs "police" to intimidate is just the beginning. Home invasion child rapists were given less time than Lucy Connelly, Alex Bellfield or Tommy Robinson go
